HFC-23

Summary

HFC-23 is used as a replacement for R13 and R503 in very low temperature refrigeration. It is also used as a clean fire suppressant as a replacement for Halon 1301. HFC-23 is most commonly used in cascade systems at an evaporating temperature of -60oC to -100oC and at a condensing temperature of approximately -10oC to -40oC. HFC-23 now has limited use due to its high Global Warming Potential (GWP).
